Joint Institute for High Temperatures of the Russian Academy of Sciences Discovers a New Phase Transition in Cesium Plasma: Abrupt Conductivity Jump and a Rare Double Critical Point

A research team from the Joint Institute for High Temperatures of the Russian Academy of Sciences (JIHT RAS / ОИВТ РАН) has achieved an important physics advance in the study of extreme high-temperature and high-pressure states: researchers have discovered a previously undescribed phase transition in cesium (Cesium) under dense plasma conditions, accompanied by a dramatic jump-like change in electrical conductivity. The study focuses on the microscopic physical behavior of matter at temperatures from 500 to 20,000 Kelvin (K) and pressures ranging from about 1 hectopascal (hPa) to several terapascals (TPa). Under such severe extreme conditions, interatomic distances are greatly compressed, matter undergoes multiple deep ionizations, and the traditional criteria for distinguishing solid, liquid, and gas states can no longer...

US PPPL Reconstructs 70-Year-Old Lawson Criterion, Proposes New Fusion Ignition Pathway of "Heat First, Fuel Later"

The Princeton Plasma Physics Laboratory (PPPL), under the U.S. Department of Energy (DOE), released its latest findings on October 5. Laboratory physicists have reconstructed the classic Lawson criterion that has been in use for over 70 years and published the results in Physical Review Letters. The research team integrated four real-world physics effects that were previously treated separately into a unified model, mapping out an entirely new fusion ignition topography. The study shows that adopting a pathway of first heating the plasma and then increasing fuel density can achieve the ignition conditions for self-sustaining burn with far less energy consumption than traditional pathways. For over 70 years, the nuclear fusion field has relied on...

ENN's "Xuanlong-50U" Device Successfully Achieves Hydrogen-Boron Fusion Reaction

In late September 2026, ENN achieved a major breakthrough in the commercialization of hydrogen-boron fusion: the Xuanlong-50U device achieved a hydrogen-boron fusion reaction. This is the first time a global commercial fusion company has achieved a hydrogen-boron fusion reaction on its own device, and also the first time China's magnetic confinement fusion device has achieved a clean neutron-free fusion reaction with advanced fuels (hydrogen-boron, deuterium-helium-3). Hydrogen-boron fusion has commercialization advantages such as being neutron-free, having abundant and easily accessible fuel, and low cost. Its product is helium (α particles), but compared with deuterium-tritium fusion, it requires higher reaction temperature and triple product, and more demanding reaction conditions. In this experiment, the ENN fusion team, through the synergy of high-energy neutral beam injection and radio-frequency waves, greatly increased the non-thermal equilibrium fast proton fraction at the first resonance peak of the hydrogen-boron reaction...
